High Performance Trivalent Finishes
Modern Plating’s research has developed Zinc-PLUS³ to meet the needs of those customers requiring the high performance of Modern’s popular Zinc-PLUS finish but in a trivalent version. All drive characteristics of our hexavalent Zinc-PLUS finish have been maintained in the new trivalent Zinc-PLUS3 finishes.

Zinc-PLUS³ eliminates the use of hexavalent chromates which have been used for many years to provide high levels of corrosion resistance. Hexavalent chromates are now being banned in many industries because they have been proven to be carcinogenic.

Zinc-PLUS ³ black will also surpass 240 hours to the first sign of white corrosion in neutral salt spray testing and over 500 hours to the first sign of red corrosion.

Zinc-PLUS ³ meets the demanding specifications of high gloss finish, good elasticity and minimal recess fill. This permits it to be used on a wide variety of part configurations. Zinc-PLUS³ offers significant cost savings when compared to other finishes offering this level of corrosion resistance. It meets all the adhesion requirements of the ASTM B-571 standard and has passed the climatic/cyclical testing of GM 9540P.
